Who makes switch-box for balance inputs?

Mikelavigne,

That is a nice looking unit. I can see why you are having a hard time letting it go. The application I'm looking at is the reverse; one XLR input splitting into two XLR outputs (one output selectable to RCA). I want to bi-amp my Martin Logans (combo electrostat & 8" woofer); Tube for electrostat & SS for 8" woofer. Due to mismatch in the input impedence of the two (100k ohms-tube vs 30k ohms-ss), I was going to add an impedence balancing circuit.

Don't see why your unit wouldn't work (may need to change some connectors/wiring). What are the dimensions? How much would you be asking for the unit? I live in Raleigh, NC.

Sleepysurf,

Have you used their LR1 pro? Is it transparent or is the sound altered?

I went to the website; looks nice. They seem flexible in meeting your specific needs.

Nope, never used one, nor heard one. Stumbled upon their site while searching for an RCA audio switchbox. I ended up getting the Niles AXP-1, which although inexpensive, sounds very transparent. BTW, I also have ML's (Aerius i's), vertically bi-amped using a Sunfire Cinema Grand Five. Sounds fantastic. I use the Niles to alternate inputs between my Squeezebox/Benchmark DAC-1 or Yamaha RXV-1000 (for movies).

Ncwogger, prior to your question yesterday; i did sell my switchbox....at least my wife is happy.

i'm not sure it could have been reconfigured to your needs......but then as i mentioned....i'm no techie. some aspects of the switcher would have no value to you such as the mute toggles and the RCA inputs.

to answer your 'other' question; the faceplate is 14" long....and each separate box for each channel is about 7" x 4" x 2".

just FYI the buyer is from Charleston.....a Gamecock fan.....sorry, i could not resist.

Ncwogger, Like I said back to back switching with switch on and without did not changed sound drastically. But you can tell direct connection without switch was slightly/very slightly better.
